AMALIA M. DONALLY, OF NEW YORK, N. Y.

BUNG FOR BOTTLERS.

SPECIFICATION forming part of Letters Patent No. 468,437, dated February9, 1892.

Application filed September 29,1891. Serial No. 407,105. (No model.)

To aZZ whom it may concern:

Be it known that I, AMALIA M. DONALLY, of the city, county, and State ofNew York, have invented a new and useful Improve ment in Bungs forBottlers; and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

My invention relates to devices employed in bottling liquids which areheavily charged with gases which it is desirable to retain as far aspossible in order to preserve the life of the liquid; and its object isto provide means for returning to the barrel or other source of supplythe gases which are set free in the bottles, and, further, to facilitatethe starting of the operation of bottling.

My invention consists, mainly, in the improved bung for bottlers usehereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of my device in use withthe associated parts in connection therewith, a barrel being representedin dotted lines; and Fig. 2 is a central section of the bung with anair-compressor connected therewith and with the head hereinafterreferred to shown removed and in section.

The bung A may be of any suitable material or shape, but is preferablymade of rubher, with a tapering neck 13 to fit snugly into the bung-holeof a barrel or other receptacle 0. The body of the bung may be hollow,as shown; but the end D should be solid and may occupy with respect tothe axis of the neck B a horizontal or vertical or any otherconvenientposition. The bung is perforated, as at E, to receive snuglythe filling-tubes F, and is also perforated, as at e, for connectionwith the gas-return tubes f. For convenience in operation, a head G isprovided with a series of nipples g to receive the ends of the gas-tubesf and with the neck g to enter the hole 6' in the bung. If desired, thehole 6 may be provided with a metallic lining-sleeve H.

In the use of my device the filling-tubes are extended through the holesin the bung to the bottom of the liquid in the barrel, while the otherends are extended into the bottle K. The gas-tubes extend from the bungto the necks of the bottles and may there be held by the hand or otherconvenient means; but

preferably a cap L is made to embrace both tubes snugly and to cover theopen mouth of the bottle.

In bottling liquids the barrel is usually supported somewhat above thebottles and the liquid flows through the tubes under atmosphericpressure. To start this siphonage when 'a fresh barrel is put in placevarious expedients are resorted to, all more or less cumbersome andundesirable. To the end that this may be readily accomplishedI have madethe head G removable from the bung with the tubes f attached thereto, sothat an air-compressor M, which I have shown as an ordinary rubber-bulbcompressor, may be inserted in its place and suflicient pressureproduced above the surface of the liquid to start it through the tubesF. When the flow has been started, the head G may be restored to placeand the operation of bottling proceeded with. During the operation thegas which would otherwise escape from the mouth of the bottle isreturned to the barrel through the bung, the return of the gas beingfacilitated and made more complete by the flow of the liquid from thebarrel, there being no other opening for the ingress of gas or air totake the place of the liquid and restore equi-- librium than through thegas-return pipes.

I claim as my invention- 1. The combination, with a filling-tube and agas-return tube, of a bung perforated to receive the filling-tube andperforated for connection with the gas-return tube, and a cap adapted toembrace both tubes snugly and to cover the open mouth of the bottle orother receptacle to be filled, substantially as shown and described.

2. The combination, with a bung for bottlers, having a neck to enter andfit the bunghole of a barrel or other receptacle andhaving a perforationto receive a filling-tube, of

a head having a neck to enter another perfo- AMALIA M. DONALLY.
